GLOBE DRAFT-SHIELD.

Application filed November 30, 1915.

To all ywhom t 'may concern.'

Be it known that I. SILAs Brno, a citizen of' the United States, residing at Chilton, in the county of Falls and State of Texas, have invented new and useful Improvements in Globe Draft-Shields, of which the following is a specification.

This invention relates to globe draftshields and the principal object of the invention is to provide a simple and efficient device which may be firmly attached to an ordinary lamp chimney or globe and which will prevent draft or sudden gusts of wind from blowing out the lamp.

Further objects of the invention will appear as the following description is read in connection with the accompanying` drawing, which forms a part of this application, and in which Figure l is a perspective view of the device. Fig. 2 is a vertical sectional view showing the device mounted upon a lamp globe.

Referring more particularly to the drawing, l represents a substantially circular body which tapers from the base to the upper end thereof so as to produce an attenuated exit 2. At the base of the body there is secured an annular flange 3 having parallel sides and overlapped freely engaged ends 4. These ends are separated as shown at 5 from the body and passing across the same is a spiral spring 6 permanently connected to a lug 7 at one end and adjustably connected to a lug S at the opposite end by means of a bolt 9 upon which is mounted a thumb nut 10. The top of the body is covered by a cap 11 having depending flanges 12 to cover the side exits 13 formed in the body. The cap is also provided with openings lu in its body portion and the body 1 is provided with apertures l5 placed immediately above the flange 3 and of somewhat smaller' diameter than the apertures 13.

`When the device is placed upon a globe as shown in Fig. 2 it is limited in its down- Specification of Letters Patent.

ward movement by lingers 16 which engage over the upper edge of the globe as shown. These fingers may be either struck up from the body of the device or riveted to the same as shown.

That is claimed is l. A device of the class described comprising a hollow frusto-conical body, an annular split ange carried thereby, adjustable means connecting the ends of said flange for drawing the latter together thereby constricting said flange, and means for preventing top draft into the globe.

2. A device of the class described comprising a hollow frusto-conical body, an annular split flange carried thereby, a yieldable connection between the opposite ends of said flange, means for adjusting the tension of said connection, and means for preventing top draft into the globe.

3. A device of the class described ccmprising a hollow frusto-conical body, an annular split flange carried thereby, means for supporting said body upon the globe, and limiting the downward movement of the body thereon, a yieldable connection between the opposite ends of said flange, means for adjusting the tension of said connection, and means for preventing the top draft into the globe.

4. A device of the class described coinprising a hollow frusto-conical body, an annular split flange carried thereby, a lug carried by the opposite ends of said flange, a spring having one end terminally secured to one' of said lugs, a bolt secured to the opposite terminal of said spring and adjustably associated with the other of said lugs whereby to constrict said flange, and means for preventing top draft into the globe.

In testimony whereof l afliX my signature in presence of two witnesses.
